Abstract
A control device for an internal combustion engine is configured to: calculate a target intake air amount and a target charging efficiency based on a target torque; control an opening degree of a throttle valve (6) based on the target intake air amount; calculate a target supercharger downstream pressure based on the target charging efficiency; detect a pressure on an upstream side of a supercharger; calculate a target compressor driving force based on the target intake air amount, the target supercharger downstream pressure, and the supercharger upstream pressure; and calculate a target bypass valve opening degree based on the target compressor driving force, to thereby control an opening degree of a bypass valve (12) provided to a bypass passage for bypassing the supercharger.
